Dual-polarized broadband magnetoelectric dipole antenna unit and antenna array for 5g base stations

Abstract

The present application discloses a dual-polarized broadband magnetoelectric dipole antenna unit and an antenna array suitable for 5G base stations, wherein the antenna unit includes a metal boxed reflection structure, a magnetoelectric dipole, a feeding structure, and a metal boxed structure. It includes a metal base plate, and the magnetoelectric dipole includes a plurality of magnetoelectric dipole units that are symmetrical and spaced apart, and each magnetoelectric dipole unit includes an upper dielectric substrate and a parallel dielectric plate below it. The medium on the surface of the upper dielectric substrate A metal patch is printed on the layer as an electric dipole, a metal coating is arranged on the parallel dielectric plate, and the metal coating and the metal base plate together form a magnetic dipole; the feeding structure includes a pair of orthogonally arranged feeders, each The bottoms of the feeders are connected to coaxial cables routed through the metal base plate. The application not only realizes dual polarization, but also has the advantages of miniaturization, wide frequency band, large gain, small backlobe, stable pattern, and large isolation, which can fully meet the needs of modern 5G communication base stations.

Description

technical field [0001] The present application relates to the technical field of mobile communication base station antennas, in particular to a dual-polarized broadband electromagnetic dipole antenna suitable for 5G base stations. Background technique [0002] With the rapid development of modern wireless communications, base station antennas are developing towards broadband, miniaturization, high gain, low cost, multi-mode, and simple structure. At the same time, with the commercial application of 5G and the successive issuance of 5G business license frequency bands by the Ministry of Industry and Information Technology to the three major operators, the demand for 5G base station antennas will experience a blowout development in recent years. In November 2017, the Ministry of Industry and Information Technology clearly planned that the 5G working frequency bands below 6GHz were 3.3-3.6GHz and 4.8-5GHz frequency bands, and planned 3.3-3.4GHZ as indoor frequency bands, and 3....

Problems solved by technology

At present, most base station antennas use dual-polarized antennas, such as microstrip antennas, etc., but traditional array antennas have disadvantages such as poor coupling, large outline, and low gain.
